Supermarket mogul John Catsimatidis wants to be the city’s next billionaire mayor — and he’s willing to do the job at a discount.

“I was a grocer, I’ll work for 99 cents,” Catsimatidis said during a press conference outside City Hall to declare his Republican mayoral candidacy.

Mayor Bloomberg, one of the wealthiest men in America, famously collects only $1 a year for the job. But Catsimatidis was quick to draw distinctions between himself and Bloomberg, painting himself as a man of the people.

“It’s not that I’m only a business person. I’m from 135th Street. I’ve never forgotten where I came from,” he said. “I’m not a Mike Bloomberg billionaire; I’m not wearing a $5,000 suit.”

Catsimatidis, who was worth an estimated $1.7 billion in 2010, according to Forbes, made it a point to tell reporters he was wearing a $99 suit for the event.

Suits aside, he is — like Bloomberg — planning to fund the campaign out of his own deep pockets.

“I don’t give a damn about the money,” the billionaire Gristedes founder said, although he refused to disclose how much of his personal fortune he’s willing to spend on the race.
